' 18 Claims. (Cl. 155-160) This invention relates to seats for automobiles and particularly to reclining seats.

Automobile manufacturers have recently found a customer demand for a front automobile seat which has the back divided into two sections, each section being adjustable to a plurality of reclining positions.

In one type of adjusting mechanism which is currently used for each back section, a plurality of rods, latches and other associated parts are exposed to the exterior of the seat. Moreover such a mechanism requires a great number of parts.

It is an object of this invention to provide a reclining seat which will obviate the aforementioned disadvantages. The reclining seat embodying the invention has a single mechanism at one end of each section of the back which serves the combined function of hinging the back section to the seat and, in addition, providing an adjusting mechanism It is a further object of this invention to provide a reclining seat having an adjusting mechanism which requires only one movement for each increment of lowering the seat back.

It is a further object of this invention to provide a reclining seat having an adjusting mechanism which is low in cost.

' to the seat frame 23.

Fig. 14 is a fragmentary side elevational view showing a modified form of the invention.

Referring to Fig. 1, a seat 20 represents a front seat of an automobile which includes a seat cushion 21 and a back cushion comprising two sections 22 mounted for. hinging movement relative to the seat cushion 21. As shown in Fig. 4 the frame for the reclining seat is made of tubular members and includes a seat frame 23 for supporting the seat cushion and back frames 24 for supporting the back cushions.

Each back frame 24 includes a bracket 25 at the lower end of the inner side thereof having a generally horizontal pin 26 thereon which projects into an opening 27 on a tubular upright 28 extending upwardly from the frame 23 (Figs. 9 and 10). By this arrangement the inner side of each back frame 24 is hinged at its lower edge The outer side of each frame 24 is hinged at its lower edge to the seat frame by an adjusting mechanism 30.

As shown in Figs. 4, 5 and 8 adjusting mechanism 30 includes a cylindrical casing 31 having a closed end wall 32 non-rotatably mounted on a fiat upright bracket 33 on the back frame 24 by means of lugs 34 projecting through openings 35 in bracket 33. The inner periphery of cylindrical casing 31 bears against the periphery of a circular bearing plate 36 to form the pivot for the back frame 24 to the seat frame 23. Bearing plate 36 is fixed to a flat upright bracket 37 by means which includes circumferentially spaced projections 38 passing through openings 39 in bracket 37 and screws 40 threaded into projections 38 (Figs. 13 and 14). Bracket 37 is fixed on frame 23.

As shown in Figs. 5 and 8 bearing plate 36 includes a centrally located pin 41 which extends axially through the center of wall 32 of cylindrical casing 31 and through an opening 42 in bracket 33. The bearing plate and. cylindrical casing are held in assembled relation by a cotter pin 43 which holds a flat washer 44 against the spring Washer 45 which, in turn, is compressed against the outer surface of bracket 33. Cylindrical casing 31 is reinforced by a ring 46 press fitted or shrunk on the outer periphery of the cylindrical casing.

Referring to Fig. 3, cylindrical casing: 31 is formed with two diametrically opposed sets of teeth 47, 48 which lie on opposite sides of pin 41. The apexes of teeth 47, 48 lie on a common circle having a diameter D. The apexes of teeth 47 are staggered slightly circumferentially relative to the apexes of teeth 48. A pawl 49 is positioned within cylindrical casing 31 for reciprocating movement between the sets of teeth 47, 48. Pawl 49 includes an opening 50 surrounding pin. 41 and elongated in the direction of movement of pawl49. -The reciprocating movement of pawl 49 is guided by spaced rails 51, 52 which are formed integrally with hearing plate 36. Pawl 49 is formed on each end thereof with a locking tooth 53 and an auxiliary tooth 54.

As further shown in Fig. 3 the length L of pawl'49 measured in a direction parallel to the line of reciprocating movement of pawl 49 is greater than the diameter D of the circle in which the apexes of the sets of teeth 47, 48 lie. By this construction when the pawl 49 is moved away from one set of teeth and toward the other set of teeth, one of the teeth 53 is in position for engagement with the teeth toward which the pawl is moved before the opposite tooth 53 moves out of engagement with the teeth away from which the pawl is moving. For example, as shown in Fig. 3 when the pawl is moved upwardly in the direction of the arrow, the lower tooth 53 is still in engagement with tooth 48 when the upper tooth 53 has moved into the space between teeth 47. By this arrangement as the pawl 49 is reciprocated a step-by-step adjustment of the back frame relative to the seat frame is insured. 7

As shown in Fig. 12 each tooth 47 has a generally flat radial surface 55 and an inclined concave surface 56. The teeth 48 of the opposite set are similarly shaped. Each tooth 53 of the pawl 49 includes a complementary flat radial surface 57 and an inclined flat surface 58. The included angle a which the radial surface 57 makes with the inclined surface 58 of the pawl is smaller than the included angle b which the radial surface 55 makes with the inclined surface 56 of the set of teeth 47. Tooth 54 of pawl 49 is shorter than tooth 53 and includes a generally radial convex surface 59 and an inclined convex surface 60, the included angle between surfaces 59 and 60 being greater than the included angle b or the included angle a. The convex surface 59 of tooth 54 is inclined slightly, at an angle of about from a radial plane and in the direction toward the adjacent tooth 53 (Fig. 12) to facilitate engagement and disengagement of the pawl 49 with the sets of teeth 47, 48.

As shown in Fig. 3 the surfaces 56 of the diametrically opposed sets of teeth incline radially outwardly and circumferentially in a direction opposite to the direction in which the back frame 24 moves from the upright to the several reclining positions. As pointed out previously and shown in Fig. 3 the teeth 47 are displaced angularly or circumferentially relative to the teeth 48 so that when the pawl is moved out of engagement with one set of teeth and into engagement with the other set of teeth the casing 31 will move angularly under the weight of the back frame 24 to a new position. For example, when the pawl 49 in Fig. 3 is moved upwardly the upper tooth 53 of the pawl is moved into a space between a pair of teeth 47 and when the lower tooth 53 of the pawl disengages from the tooth 48, casing 32 together with back frame 24 will rotate in the direction of the arrow to bring radial surface 57 of the upper tooth 53 into contact with radial surface 55 of one of the teeth 47. In the uppermost position of the seat back, and the succeeding three adjusted positions, a tooth 54 on the pawl contacts the radial surface of an adjacent tooth on the casing, thus distributing the load on two teeth instead of one. In the fifth adjusted position of the seat back only a tooth 53 is engaged with a tooth 47 and in the sixth position of the seat back only a tooth 53 is engaged with a tooth 48.

Means are provided for manually reciprocating the pawl 49 and include slots 61 through bearing plate 36 and bracket 37 through which a pin 62 on pawl 49 projects. As shown in Figs. 2, 5 and 8 a lever 63 is pivoted and tooth 54 of pawl 49 are engaged with teeth 47. When the lever 63 is actuated to move pawl 49 downwardly the lower tooth 53 of the pawl 49 moves into the space between teeth 48 and thereafter the upper tooth 53 moves out of engagement with the upper set of teeth 47 permitting the back frame 24 to move under its own weight in a clockwise direction as shown in Fig. 6 to a new position. The movement of the seat frame more than a predetermined amount is prevented by the contact of one of the teeth 48 with tooth S3 and tooth 54 on the lower end of the pawl. When the lever. 63 is again actuated to raise the pawl another stepped movement of the back frame 24 is produced. Successive movement of the lever causes successive movement of the back frame until the back frame is in the lowered position shown in Fig. 11 with the pawl out of engagement with any of the teeth. In this position the back frame is normally supported by a bracket or other support on the floor of the automobile.

In order to elevate back frame 24 it is only necessary to grasp the back frame and move it manually upwardly.

- This movement will cause the pawl to be reciprocated to upright bracket 37 on the seat frame by means of a bolt 64. Lugs 65 bent inwardly from one end of the lever are adapted to engage the pin 62 on pawl 49 so that when the lever is actuated the pin 62 is moved upwardly and downwardly as shown in Fig. 2 to reciprocate the pawl 49. The other end of lever 63 is bent outwardly as at 66 through an opening 67 in protective cover 68. A knob 69 is mounted on the end of the lever to provide a means for grasping the lever 63 in order to move it. A hairpin spring 70 is provided to yieldingly urge the pawl into engagement with each of the sets of teeth. Spring 70 comprises a loop of wire with projecting arms, one arm being engaged with the end of the lever 63 as at 71 and the other arm being engaged with the bracket 37 as at 72. At the lever 63 is moved, the point 71 on the lever 63 is moved from one side of a center line connecting point 72 and the axis of bolt 64 to the other side so that the spring passes over center to yieldingly urge the lever in each of its positions and, in

.turn, yieldingly urge the pawl into engagement with each back and forth under the action of teeth 47, 48 on the pawl. Specifically, the inclined surfaces 56 of teeth 47, 48 act on the teeth 53 to cause the reciprocation of the pawl. By this arrangement the back frame will be elevated in one continuous movement. Upward movement of the back frame is limited to the position shown in Fig. 6 by contact of a stop 75 with guide rail 52 as shown in Fig. 6.

In the operation of the seat-adjusting mechanism it has been found that the convex surfaces 56 on the teeth 47, 48 prevent locking or binding of the pawl 49 when the .back is elevated. By this arrangement when the back, is moved upwardly toward an upright position there" is no undesirable locking friction between the end of teeth 53 and the inclined surface 56 of the teeth 47, 48 t2nd the pawl reciprocates freely between the sets of tee v A modified form of pawl-actuating mechanism is shown in Fig. 14 wherein the operating lever 63 is replaced by a crank 76 pivoted to plate 37. The end of crank 76 is connected to the shaft 77 of a double-acting solenoid 78 by means of a link 79. The double-acting solenoid 78 is controlled by a manually operable switch 80 so that upon manipulation of the switch the crank 76 is successively moved in opposite directions. By this arrangement each time the switch 80 is operated the crank 76 is moved either in one direction or another to move the pawl 49 either upwardly or downwardly.

It can thus be seen that the resulting reclining seat not only can be readily adjusted, but in addition the adjusting mechanism is compact and suflieiently protected so that it will not be damaged by the normal wear and tear imposed on the seat by persons entering and leaving the automobile. In addition, the reclining seat mechanism may be manufactured at low cost.

Because the hinge line of the back frame which passes through inner pin 26 and outer pin 41 is located near the end of the seat frame, it is possible to obtain a relatively flat unit when the seat back is in its lowermost position.
